I think conversational fluency takes a bit of gumption, in that you need to find people to talk to. You can join Japanese/English discord servers, get into the voice chats and listen and learn. iTalki is an app where you can schedule conversation time with tutors. There are also lots of YouTube channels that focus on natural Japanese and not textbook learning. But the theme with all of these is that no one is guiding you through, there's no easy to follow path and it is very DIY. I think drilling kanji catches people because it feels like a gamified progress that ends in fluency, if only you could drill enough kanji. So it becomes a morale failing in someones mind, rather than seeing it as a failure to teach.
